Area Forecast Discussion National Weather Service Mount Holly NJ 300 PM EST Fri Nov 22 2019

SYNOPSIS. A cold front moves offshore by this evening, then high pressure builds in tonight and Saturday morning before moving offshore. Low pressure tracks near our coastal areas later Saturday night and Sunday morning before moving offshore of New England while strengthening through Sunday night. High pressure slides to our south Monday and then offshore Tuesday. The next cold front arrives Wednesday followed by high pressure later Thursday and Friday.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. The majority of the rain showers have moved offshore at this hour and the cold front is quickly making its way toward the coast. Northwesterly winds behind the front will diminish through the evening as skies clear. High pressure will build through the overnight hours allowing colder and drier air to filter into the region. Temperatures will depend on how quickly winds drop off, but should generally be within a few degrees of 30 in most places.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY/. By early Saturday, high pressure across our region will quickly dissipate as low pressure moves from the Tennessee Valley, across the Appalachians, through the Mid-Atlantic, then offshore by Sunday morning. Clouds will increase from southwest to northeast by late Saturday afternoon and into the evening hours. High temperatures should peak in the mid to upper 40s for most, but may see a few areas in the far south/east reach 50 degrees.

A shield of light to moderate rain will accompany the low as it moves toward and cross the region. Rain is forecast to move into the area by the evening hours and last through much of the overnight hours and even into Sunday morning. As the low moves offshore, it will be located under the left exit region of its parent trough, which will be favorable for rapid intensification. As such, expecting the trend of northwest banding shown in the latest guidance to continue. This would result in the continuation of precipitation well after daybreak Sunday and I have updated the forecast to reflect this trend.

As far as precip type goes, there has been a slight warming trend in the guidance over the past couple of runs. Therefore, I increased temperatures a bit across the northwest. As a result, backed off quite a bit on the wintry precip in the forecast, however still expecting some light wintry precip in the form of freezing rain, possibly mixing with sleet or snow, overnight Saturday night. Lows Saturday night will generally be in the mid 30s to around 40 degrees for most outside of the higher terrain of the southern Poconos and NW NJ. As the center of the low draws near by around daybreak Sunday, temperatures should favor precip type to switch back to mostly rain if not already. Could see a few snow flakes as the precip ends across the far northern portion of the forecast area Sunday morning.

The low pressure will move away from the forecast area through the remainder of Sunday and skies will clear from west to east. Northwesterly winds of 10-15 mph behind the departing system can be expected with some gusts up to 25 mph. High temperatures will be in the 40s to near 50 degrees.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. Summary . Turning warmer through the first half of next week ahead of a strong cold front then blustery for Thanksgiving day. Precipitation chances are centered mostly on Wednesday.

Synoptic Overview . A closed low will exit coastal New England and move across the Canadian Maritimes Sunday night and Monday, then the flow turns more zonal for early next week. A trough amplifying eastward from the Plains Tuesday will result in a building downstream ridge and warm air advection across the East. The aforementioned trough moves across the Great Lakes and Northeast Wednesday, pulling a strong cold front across our region as strengthening low pressure tracks well to our north. The trough gradually moves out Thursday as a ridge gets closer from the west, and this results in surface high pressure building into our region Thursday night and Friday.

For Sunday night and Monday . Strong low pressure will track near Cape Cod Sunday evening then northeastward into Monday. The flow in its wake in the East tends to turn more zonal into Monday, with surface high pressure sliding across the Southeast (it extends into our area on Monday). This high then shifts offshore Monday night allowing a northwesterly flow at the surface to diminish Sunday night into Monday before turning west to southwest. It will be chilly Sunday night and as the winds diminish temperatures could drop off faster during the evening especially in the typically colder locales. As the flow backs some Sunday night and especially Monday, warm air advection starts to increase however this looks more pronounced Monday night. This in combination with more of a westerly flow aloft may result in some high level clouds starting to arrive. Overall, chilly Sunday night and then milder Monday afternoon compared to Sunday.

For Tuesday and Wednesday . As an upper-level trough amplifies eastward from the Plains Tuesday, a downstream ridge strengthens surface high pressure off the East Coast. This will result in a southerly flow across the region with an uptick in the low-level warm air advection. This will translate to high temperatures both days well into the 50's for much of the area with some places topping 60 degrees especially Wednesday. Some increase in the clouds takes place especially Tuesday night and Wednesday, and despite the warm air advection the bulk of the lift should remain to our northwest. A surface low will track across the Great Lakes Tuesday night and then continue northeastward Wednesday, pulling a strong cold front across our region during Wednesday. The main forcing may remain just to our west and north though, with much of the guidance showing not much with the cold frontal passage in our area. Given the depth of the incoming upper-level trough, maintained chance PoPs mainly for Wednesday as the cold front moves through. The southerly flow ahead of the front may get a little gusty especially in the coastal plain, then gusty northwesterly winds in its wake Wednesday night.

For Thursday and Friday . As the Wednesday systems exits New England, ridging slides eastward from the Great Lakes to the Gulf coast. This will result in high pressure building eastward and arriving over our area during Friday. There looks to be a tightened pressure gradient in place as low pressure gradually moves into the Canadian Maritimes, therefore much of this time frame will feature gusty winds (blustery for Thanksgiving Day). It looks to be dry though with much drier air advecting across the region.

AVIATION /20Z FRIDAY THROUGH WEDNESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Tonight . VFR conditions are likely through the overnight hours. Northwesterly winds of 10 to 15 kt will gradually diminish overnight and veer to westerly. Medium confidence.

Saturday . VFR conditions are likely through the day time hours. Mid level clouds are expected to advect in late in the day, but at this point it looks like MVFR or even IFR ceilings should hold off until after sunset. Westerly winds becoming southwesterly through the day, with speeds less than 10 kt.

Outlook . Sunday night and Monday . VFR. West-northwest winds diminishing to 10 knots or less, becoming west to southwest Monday. Moderate confidence.

Tuesday . VFR. Light and variable winds becoming south-southwest around 5 knots. Moderate confidence.

Wednesday . A period of Sub-VFR conditions and some showers are possible. Southwest winds 10-15 knots with gusts to 20 knots, becoming west to northwest late with gusts to 25 knots. Low confidence with the timing of any sub-VFR conditions and wind shift.

MARINE. In the wake of this afternoon's cold front, northwesterly winds gusting near or above 25 kt are expected on all waters, with the exception of the northern Delaware Bay where gusts may fall just short of Small Craft Advisory criteria.

Winds and seas should gradually diminish late tonight. By Saturday, winds and seas are expected to be below SCA criteria on all waters.

Outlook . Sunday night . Northwesterly winds diminish below Small Craft Advisory criteria.

Monday and Tuesday . The conditions are anticipated to be below Small Craft Advisory criteria. Southerly winds start to increase Tuesday night.

Wednesday . A Small Craft Advisory is probable. Southerly winds becoming west to northwest with the passage of a cold front.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory until 6 AM EST Saturday for ANZ450>455. Small Craft Advisory until 10 PM EST this evening for ANZ431.
